1 Claim. 1

This invention relates to means for applyin heat locally to the humanbody, and pertains more particularly to a portable heatapplicator.

One object of the present inven'tion'is to provide an electrical heatapplicator having a portable source of electricity which adapts it forutilization at any time and anywhere.

Another object of the present invention is to provide with an electricalheat applicator insulative means whereby the heat permitted to penetrateto a user is effectively controlled.

Another object of the present invention is to provide with electricalheat applicating means a plurality of difiere'ntially heat insulativemeans which may be selectively utilized for-controlling the heatpermitted to penetrate to a user.

Another object of the present invention is to provide with an electricalheat applicator, means whereby heat is absorbed and retained while themeans for heating the applicator'is effective and which serves as asource of heat after the applicator heating means is renderedineffective.

Still another object of the present invention is to provide with aportable heat applicating means, means whereby insulative heatcontrolling means and heat retaining means may be selectively andinterchangeably utilized therewith.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claim in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. l is an isometric View of the heating pad made in accordance withthe first embodiment of the invention.

' Fig. i is an isometric view of a second embodiment of the invention.

Fig. 8 is a sectional view taken along the lines 8-8 in Fig. 7.

Fig. 9 is an isometric view of an insulating pad adapted for employmentwith the second embodiment and broken away to illustrate the internalconstruction thereof. Y

,Fig. 10 is an isometric view of a heat retainer also adapted foremployment with the second embodiment and also broken away to illustratethe interior thereof. a

The means for applying heat to the human body, according to the firstform of the present invention shown in Figs. 1 to 6, includes a heatingpad it which comprises a cover H of pliant and non-inflammable material,a heating element 1 2. enclosed in said cover, a plurality of male snapfasteners l3 arranged spacedly on the rear face of the cover adjacentthe marginal edges thereof, and a buckling means [4 whereby the pad maybe secured about a portion of the human body.

Provided for supplying current to the said heating element !2 throughsuitably insulated wires It is a battery box 18, which includes a switchll for controlling the current emanating from batteries therein and isof dimensions permitting it to be carried in a pocket of the wearersclothing.

The arrangement this far described may be utilized as is for theapplication of heat to a particular portion of the human body. However,it is a well-known fact that certain persons are particularly sensitiveto heat and. cannot comfortably endure too high a degree thereof ontheir epidermis. For this reason the present invention, as seen in Figs.2 and 3, contemplates the provision of an insulative pad 20. Said pad 20comprises a pliant covering 2| of any suitable material and includestherein a layer of any suitable heat insulative material 22. Providedfor securing the pad 29 to the heating pad I0 is a plurality of femalesnap fasteners 23 arranged spacedly adjacent the marginal edges of saidpad 2i! and adapted for cooperation with the male fasteners l3 on thesaid heating pad cover II. It will be seen that when the just describedarrangement is in effective use there will be an insulative andprotective layer of material between the heating pad and the usersepidermis and this, in effect, controls the heat permitted to penetratethrough to said users epidermis.

It will also be seen that a plurality of differentially insulative padsmay be provided for selective employment with the heating pad and inthis manner said heating pad may be adapted for use by a variety ofpersons.

Also provided for combined use with said heating pad Ill is a heatretainer 25 which, as seen in Figs. 4, 5 and 6, is formed of anysuitable waterproof material such as rubber, and includes in itsconstruction a plurality of water-filled sealed compartments 26.Provided spacedly arranged and adjacent the marginal edges of the saidheat retainer 25 is a plurality of female snap fasteners 27, whichfasteners are adapted for cooperation with the male fasteners I3 carriedon the said heating pad Hl.

lhe just described arrangement, when detachably secured to the pad In bythe mentioned fasteners, is adapted to have the water in thecompartments 26 heated while the pad 10 is in operation. For aconsiderable degree of time after the pad I is rendered ineffective, thewater which retained the heat will be effective for serving as a sourceof heat.

As seen in Figs. 7 and 8, a second embodiment of the inventioncontemplates a heating garment 3!! including a vest 3|, a heating pad 32secured to saidvest as to provide a pocket 33 all about the said vestand comprising a cover 34 of suitable pliant and non-inflammablematerial, a heating element 35 enclosed in said cover, and a batteryencasing box 36 affixed to said vest and having a switch 37 forcontrolling a flow of current through wires 38 to the said element 35.

This garment is efiective for applying heat to the body when same isrequired to remedy certain illnesses, for warming spectators of coldweather sports, or for general cold Weather comfort.

As seen in Fig. 9, the present embodiment also contemplates theprovision of an insulative pad 45. Said pad Iii comprises a covering 4|of suitable pliant material which encloses a layer of heat insulativematerial 42. This insulative pad, when inserted in the pocket 33 of theheating garment 39, is efiective for controlling the amount of heatpermitted to penetrate from the heating pad 32 to the Wearers body. Thisembodiment also contemplates the provision of a plurality ofinterchangeable and differentially insulative pads for controlling theheat penetration variably.

Now, as seen in Fig. 10, a heat retainer 45 is also adapted forinsertion in the said garment pocket 33. Said retainer 45 is similar tothat described above with regard to the first embodiment in that it,too, is formed of rubber, or like waterproof material, and includes aplurality of water-filled sealed compartments 46. When the retainer 45is inserted in the garment pocket 33 and the heating pad 32 iseffective, the water in the said 4 compartments 46 will be heated. Thus,the heated water is adapted to serve eflectively as a source of heat forthe wearer after the heating pad is rendered ineffective or after thebatteries supplying current to the heating element 35 have gone dead.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claim.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:

In an article 01'- the class described having an electrically heated padfor engagement against a portion of the human body to be heat treated, aheat retaining pad positioned against the inner face of the heated pad,fastener elements mounted on the inner face of the heated pad, andcomplementary fastener elements mounted on the outer face of said heatretaining pad and engaged with said first-mentioned fastener elementsremovably securing said heat retaining pad to the heated pad, soconstructed and arranged that said heat retaining pad can be completelyremoved to have the heated pad engaged flat against the body, said heatretaining pad comprising an envelope of waterproof material having aplurality of waterproof compartments, and a quantity of water sealed ineach of said compartments.
